Production & Quality
1.Production Process
Crushing→Mixing→Shaping→Drying→Firing→Inspection→Packing shipment
2.Quality Control
a.According to the chemical content,raw materials are classified into different levels to ensure quality of brick first.
b.During the production,every brick will be weighed twice strictly to reduce the error of weight .
c.Before delivery, the inspectors will inspect the size,appearance,physical and chemical properties of brick again in factory.
